Orange-Flavored Springerle Cookies
This recipe is the most genuine, using hartshorn (baker's ammonia) as the leavening agent to add crispness. Baking powder can be used as an alternative. Store them in an airtight container for a week before serving, allowing the flavors to develop. The cookies can be stored at room temperature for up to 1 month.
If using baking powder instead of hartshorn, skip step 2. Add 1/2 teaspoon baking powder with the cake flour in step 3.
If using a springerle rolling pin, work on a surface lower than a kitchen counter top so as to not push the dough and stretch the impressions.
